IMPROVEMENT IN MACHINES'FOR PICKINGHOAKUM, CURLED HAIR, dc.

Specilcation forming` part of Letters Patent No. 962, (lated October 5, 1839.

y may be successfully operated upon by the saidv machinery, of which the following is a specifieation. y y

.These improvements, the principlesof the saine, and the manner in which I have contemplated their application, together with such parts, inventions, or combinations I claim as my discoveries and hold to be origi-` nal and new, I have herein set forth and described,` Which description, together with the .accompanying drawings, herein referred' to,

compose my specification.

Figure 1, Plate 1, and Fig. 2, Plate 2, represent side and top views of the machine.

A.A A, Figs. 1and2, is astrong frame, of wood, iron, or other suitable material, 'constructed' as seen in the drawings, or otherwise shaped and formed to answer the purpose of supporting the machinery ,attached thereto.

CB, Fig. 2, is a loose and C'a fast pulley .on the main shaft D, Figs. 2 and 1. The belt from the drum which drives 'the machine passes around either of these pulleys, ascenvenience requires. E E E E, Figs. 1 and 2, is a large drum or cylinder on the shaft D, which shaft rests and revolves in suitable bearings attached to the sides of the frame-work. Teeth aa a, of steel orotherpropermaterial,areinsertedatsuitable distances apart over thewhole outer. surface of the cylinder On the axis D4 ofthe cylinderv E a pulley, F F, is xed, around which a belt, G G, passes to another pulley,l II H, on a horizontal shaft, I I. Onthe shaft I is a pulley, L, Figs. 1 and 2, around and from which a belt, KK, passes to and over a pulley, M, on the extremity of the shaft or axis N ofanother cylinder, O, as seen in dotted lines in Fig. 1.

P Q R, Figs. 1 and2, are smaller cylinders,

having their peripheries or surfaces coveredk with teeth b b b in a similar manner to the cylinder E. The teeth of these different cylinders playin the intersticcs or spaces between the teeth a.

S S, Fig. 2, is a pulley on the extremity of.

from the latter the fibrous material.

the` axis of the cylinder I. From this pulley a belt, T, proceeds to' and around a pulley, Il, onthe end of the shaft I. By the side of this latter pulley is'another and smaller pulley,V, over which a belt, WV, passes' to and around another pulley, X, Figs. 2 and 1., on a shaft, Y Y. A small cylindrical roller, Z, is` placed on the shaft Y, around which roller an endless apron, c c, is stretched, and passes `from thence to and over another small roller, d, Fig. 1. t y

The material to be operated on is placed lengthwise on this revolving apron, and is-received at the roller d, between the teeth of the cylinders Oandl?. A small roller e, is pressen down on the material by weights 7L h on levers F F, whose fulcra are at g g, Figs. 1 andr2. `The 'extremities of the axis of the roller e revolve incylindrical holes in the levers f By moving the weights 7L h. to different positions on theleversf f the pressure of the roller e on the material as it passes between it and the apron c may be regulated at pleasure. The hair or oakum is received from the feedingapron upon the teethof the cylinders O and I?. The teeth of the great cylinder E, re-

volving ata very rapid and much faster .ve-

locity than O and P, draw off or take away The cylinders Q vand R, revolving at slower speed than the main cylinder E, raise up the fibers, so that they may be drawn ol'for away from the same by the curved teeth of the dofing-cylinder A', as seen in Fig. 1. The directions .in which these different cylinders revolve are denoted in the drawings by arrows.

The dofELng-cylinder A is driven by a crossed belt, B5B', passing over ,pulleys GD, the former on the axis D ofthe cylinder E, and the latter on the axis K ofthe cylinder A. For driving the cylinders R and Q, belts E H pass around pulleys DFG I on the axis of these cylinders, Figs. 1 and 2.

A fan, K K', Fig. 1, revolving on an axis, L',

lhas teeth 'Z Z Z xe in its edges, which, as it revolves, play between 'the teeth 71 't' of the doffing-cylinder, and not only remove the bcrs from thesame, but blow or scatter them out of the box L, in which said fan revolves. The f a'niK is as long as the cylinder A', 'and is driven by a crossed belt, M', passing over4 a;

pulley, O O', on the shaft I, and thence around ,the pulleyN*l on the shaft L of the fan K',

Figs. l and 2. The different cylinders are covered with teeth throughout their lengths, although' but two lines of teeth are represented inliig. 2 on each.

y Before submitting the curled hair or tarrcd rope tothe action of the machine I prepare it by means of the apparatus connected with the t,frame-work and shaft L' of the fan K. p Onl the extremity of the shaft L a loose. pulley,

' M', Plate 2, of any suitable size', is placed. Above this loose pulley, and to the side of the upper brace, O', .of fthe frame-work, I place two small pulleys, N N, on the axis ot' two hooks, 1? P.- Around thesethree pulleys a driving-belt, Q', passes. Toy the side of the loose pulley M is attached a rectangular piece of iron, R', having two small pins, s s', projjecting therefrom. By m/eans of a common clutch, T', (such as mechanics lgenerally use,) with arms x x', and lever U', moving on a fulcruni, V', the loose pulley lWmay be locked-to the shaft L whenever necessary, so as to put the hooks l?l 1? in rapid motion.

ing the end of the rope of twisted hairor the tarred rope which is to he reduced to oakum, (the latterbeiug' first soaked i'n hot water,) to v either of the hooks l I, it may be uutwisted.

By attach-A It is than ,in this -Seite laid upon the feedingapron and passed through the machiue,whieh separates the fibers and prepares it for the purpose for which it is intended.

4 The size of the pulleys which give motion to Athe cylinders, as well as the cylinders and other parts ofthe machine, may be varied according to' convenience, and the whole constructed of any suitable materials, as may be required.'l

In the above'ma-chinery I do not claim the invention `of any particular parts, as I am aware thateylinders with teeth projecting therefrom have been heretofore used; .but

I claimy 'Ihe arrangement 'of the whole, and their combination together, forming a machine for the purposes hereinabove specified.

In testimony that the above'is a true specilicatiou of my said invention I have hereto set my hand this 12th day of June,iu the year 4isf-ss.
